Application led August 25, 19M.

To all whom t may concern:

Be it known that I, WALTER E. BARNARD, a citizen of the United States,residing in Brooklyn borough, in the /county of Kings, city and State ofNew York, have invented useful Improvements in Type-Writing Machines, ofwhich the following is a specification.

This invention relates to means coperating with a revoluble typewriterplaten, to determine the position of the end of the work-sheet, or thecompletion of writing of a predetermined number of lines upon saidsheet.

One of the objects of the invention is to provide simple and improvedmeans for visually informing the operator when a predetermined number oflines have been written upon the worksheet, and to indicate that thework-sheet has reached a position for the last line of writing thereon.

This object is attained by the employment of a scale in the form of aring or annulus which is mounted at one end of the platen to rotatetherewith and to be independently revoluble for relative adjustment,said ring being provided around its peripheral surface with numberedgraduations which cor* respond in number with the teeth upon the linespacing wheel. These graduations pass by a fixed indicator. The numbersupon the ring are arranged progressively in the direction of theadvancing rotation of the platen, so that with the worksheet inserted inthe machine and the ring adjusted with its zero mark at the indicator,the ring may be rotated to bring a space thereon containing a numeralrepresenting the number of lines it is desired to write upon the sheetto said indicator. Then upon operating the line-spacing mechanism untilthe platen has advanced the desired number of spaces, the ring will haveadvanced in those operations to bring its zero mark back to theindicator and will thus visually inform the operator that the desirednumber of lines has been written. The space containing the zero mark ispreferably distinguished by bearing a contrasting color, so that the eyeof the operator may be readily arrested thereby.

Another object is to indicate that the bottom edge of the work-sheet isjust leaving the lower feed rolls, whereby the operator may know thatonly a certain number of lines may still be written before said bottomSpecification of Letters Patent.

edge of the work-sheet will lAssuming the distance between said feedrolls and the printing'line upon the platen to be equal to five linespaces, then the space upon the ring bearing the numeral 5 may 'alsohave a distinguishing color, in tor may be readily informed of saidfact.

Obviously the ring will be operative with work-sheets upon which agreater number of lines are required to be written than the number ofspaces contained upon said ring. Assuming for example that the ringbears thirty-three spaces, and that forty-three lines are desired to bewritten, the ring should be adjusted with its numeral l0 at theindicator, the number ten being necessary in addition to thethirty-three spaces on the ring to complete the forty-three lines thatare to be written. The platen will then rotate one revolution plus thatportion of a revolution comprising ten line-spacing operations in orderto bring the ring with its zero mark to the indicator; the passing ofthe zero mark at the end of the first ten spaces being allowed for bythe operator.

Tn conjunction with the numbered ring aforesaid, my invention includes afurther visu ual indication informing the operators, at certain stagesin the progress of the work-sheet, of the number of lines remaining tobewritten thereon in order that the operator may make due allowance.Numeral indications are arranged upon the paper table, or upon anattachment thereto, said numeral indications being consecutive andcapable of exposure or indication as the bottom edge of the worksheetpasses thereover or adjacent thereto in the feed of said work-sheet. Thenumbers aforesaid diminish consecutively downwardly and are exposed orindicated during the passage of the work-sheets thereover to designatethe number of line-spaces remaining before the bottom edge of theworksheet reaches the point upon the platen where the last line ofwriting is to be performed.

The numeral indications at the introductory side of the platen may beprovided on a numeral plate adjustable lengthwise of the platen topositions corresponding to the poorder that the opera- A sitions of thework-sheets along the platen.

The numeral plate may be provided withanup-turned ange, or other means enabling it to be gaged to theworksheet by being set up to the lateral edge of the work-sheet. used asa gage for 'positioning the worksheet to correspond with the setting ofthe gage, and squaring the sheet to the'platen. The numerals on saidplate provide an index enabling the scale or numbering on the platen tobe set to correspond to the position of the work-sheet.

Other features and advantages will hereinafter appear.

In the accompanying drawing,

Fig. 2 is a vertical sectional view of the end portion of a platen withthe adjustable computing yring thereon. n

Fig.r 3 is a detail view of the computing ring with indicator, showingthe work-sheet leaving theL feed rolls.

Fig. l is a similar view showing the work-y sheet in position forwriting the last line thereon.

Fig. 5 is an end elevation, partly in section,

showing the method of supporting the computing ring upon the platen. fFig. 6 is a front elevation of the platen with indicating means, showingthe method of indicating the number of lines remaining to be writtenupon a work-sheet.

1n the present example of my invention, it

is shown as arranged with relation to an` Underwood typewriting machinehaving a platen 1, line-spacing wheel 2, platen frame 3, paper table 4,and lower forward feed rolls 5. The paper fingers 6 with their rolls 7bearing upon the platen surface are also illustrated, and the line ofprinting upon the platen is indicated by the position of a typebar 8.

The meanswhereby the number of lines desired to be written upon `awork-sheet may be registered to inform the operator of the completion ofwriting that number of lines, consists of a ring or cap 9, loosely ttingover the periphery of the platen 1, at one end thereof, ythe drawing inthis example showing said ring 9 applied to the righto graduations 10,forming spaces which contain numerals arranged consecutively from 1 to32, the ordination ascending in the direction of theadvance rotation ofthe platen;

said ring having an exterior annular knurled Said ange may also beyportion 11, whereby it ymay be grasped for purposes of rotationin-adjustment. The

rring 9 has an inwardly directed flange portion 1'2 t0 lie over theplaten end 13 and to be revolubly supported thereon, as by the heads ofscrews 14 secured in the platen end; said screw heads or the likeserving to hold `the flange 12 from withdrawal while allowing the ringto be rotated. Tensional means are provided to retard or prevent the toofree rotation of said ring 9, such for example as springs 15 inserted inrecesses 16 in the' line-spacingoperations, the ring 9 will beangraduations representing thirty-three spaces,

and 1 have shown these spaces occupied respectively with the zero markand the numerals from 1 to 32 inclusive. The zero space is to be pointedto by the indicator when the platen is line-spaced after completing thelast line of writing upon the work-sheet, and the ring 9 may be turnedby hand, after the work-sheet has been adjusted upon the platen to theposition for the first line of writing, to bring in conjunction f withthe indicator the numeral upon the 'ring representing the number oflines to be written, or the number representing the number of lines tobe written in excess of the number of spaces upon the ring, whereuponwhen the plateny in its line-spacing operations within the limits of acomplete revolution brings the zero upon the ring to the indicator, theoperator will thereby be informed that the predetermined number of lineshave been writf ten. When the number of lines to be written is in excessof the number of line-spaces comprised in a single revolution of theplaten', then the first passing of the zero mark upon the ring will benoted, and writing will cease when said zero mark for the second timealines with the indicator, thereby denoting the completion of thepredetermined number of lines of writing.

The space upon the ring bearing the zero mark may be distinguished ashaving a distinct or contrasting color, and similarly a space bearing anumeral which may represent the distance in line-spaces from the lowerforward feed-rools to the printing line on the platen is similarlydistinguished.

The paper table, as 4, bears upon its sur-- face certain numeralindications in upward sequence at line-space intervals apart todesignate the distances in numbers of linespaces lying `between thosenumeral indicalos tions and the printing point on the platen through thepath traveled by the work-sheet. These numeral indications are usuallycovered by the lower portion of the worksheet while its leading edge isadvancing over the printing surface in the initial portion of itstravel. But as the work-sheet continues to advance, of finally uncoversthe aforesaid numeral indications in succession, and thereby affordspositive information to the operator that there remain upon thework-sheet spaces for writing the number of lines represented by theparticular numeral indication which the lower edge of covered or is inalinement with when noted.

The information thus furnished is valuable` in a corollary sense as afactor of information in informing they operator, in advance of theadvice furnished by the ring 9 of the completion of the predeterminednumber of lines of writing, that, at the time when the lower edge of thework-sheet is passing from view over the paper table, a particularnumber of lines may at that stage still be written upon the work-sheet.

The index at the introductory side of the platen, comprises the numeralindications which are represented in Fig. l as inclusive of theremaining 18 to 26 line-spaces. These numerals are preferably carried ona numeral plate 18 adjustable along the paper table to correspond totheposition of the adjacent side edge` of the work-sheet. The numerals arethus positioned to always be covered by the work-sheet until the endedge\ of the worksheet passes beyond the numbers to expose them to view.As the numeral plate is gaged to the work-sheet, the numerals areuniformly positioned in coperative relation to each work-sheet,regardless of the position of the latter lengthwise of the platen. Eachnumber is brought to View only as the work-sheet reaches the position tobe designated by said number, and is then in immediate proximity to orin contact with the sheet, so that all liability 1s avoided of the indexbeing incorrectly read by associating the wrong number with the sheetwhen the latter is at any particular position. l

The index at the paper table provides a convenient means for setting theindex wheel on the platen, as it is simply necessary to set said wheelso that the index 17 points to the numeral on the wheel corresponding tothe numeral disclosed to view at the end edge of the work-sheet. Theindex wheel may be thus set at any time after the work-sheet has passedbeyond the highthe bottom edge therethe work-sheet has last unestnumber' on the index at the paper table, until the work-sheet has passedbeyond the lowest number indicated on said table. If the work-sheet hasbeen fed beyond the range of the numerals at said table before the indexwheel has been set, the latter may still be set by rst rotating theplaten backward to bring the work-sheet within the range of the numeralsat said table, the index wheel being then set and the work-sheet againadvanced to position for continuing the printing.

Variations may be resorted to within the scope of t-he invention, andportions of the improvements may be used without others.

Having thus describedvmy invention, I claim:

l. In a typewriting machine, the combination with a platen rotatablethrough linespaces of a predetermined extent, of a paper shelf at theintroductory side of the platen, a side-gage for the work-sheets, saidsidegage having a plate portion to underlie the work-sheet, said plateportion bearing numeral indications, each indication representing thenumber of lines which may still be written on a work-sheetV carried bythe platen, said side-gage being adjustable along the paper shelf so asto be engageable by a work-sheet of any width, and so that each numberis brought to view only as the worksheet reaches a position to bedesignated by said number, and so that said number is then in immediateproximity or in contact with the sheet, whereby liability of error inreading the indications is avoided.

2. In a typewriting machine, the combination with a rotary platen, of arotary indicator mounted thereon, said indicator formed of sheet metaland comprising a ring surrounding the platen at the end thereof andextending a substantial distance beyond the platen end, the outer edgeof the ring being curved inwardly toward the platen axis and backwardlytoward the platen end and terminating in an annular iange lying Hatagainst the end of the platen, holding screws in the ends of the platenwith their heads projecting over said liange to thereby hold theindicator on the platen to permit rotation thereof relatively to theplaten, and springs interposed between said flange and the platen tofrictionally retard the rotation of the indicator relative to the platenand cause it to rotate with the platen.
